Wow, you guys are throwing out some big number for horse power!!! How fast you guys want to go???? 650HP??? This is not a fat ass termi you guys are building... 450hp your going high 10s??? You guys...

Many guys just flip around stock headers and build a y pipe to the turbo, you can buy turbo kits for a fox all day on ebay. But with it being an Rx7, you can make a custom set of heards, not to hard...
